Convert XLSX (Excel) to FODS

The XLSX file extension, standing for "Excel Spreadsheet", represents a widely used format for Microsoft Excel spreadsheets. Introduced in Excel 2007, XLSX replaced the older XLS format, utilizing the Office Open XML (OOXML) standard to store data more efficiently and reduce file size. It supports advanced features such as pivot tables, charts, formulas, and macros, essential for data analysis and reporting in various professional settings. The transition to XLSX provided enhanced security, improved data recovery, and greater compatibility with other software applications, solidifying its status as a pivotal tool in data management and business intelligence.

The FODS (OpenDocument Flat XML Spreadsheet) file extension, developed by Oracle, is used for storing spreadsheet data in a plain XML format, making it more human-readable and easier to generate automatically without a spreadsheet editor. Unlike the more common ODS format, which uses a ZIP container, FODS files are not supported by Microsoft Excel but can be opened with OpenOffice Calc. This format was introduced as part of the ODF 1.2 specifications by OASIS.
